SWAGING DEVICE.

ASPECIFICA'IION forming part of Letters Patent No. 402,045, dated April23, 1889.

Application tiled August 30, 1888.

Be it known that I, JOSEPH TAYLOR, a citizen of the United States ofAmerica, residing at Shingle Springs, in the county lof El Dorado andState of California, have invented certain new and useful Improvementsin Swaging-Machines; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers. skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to lettersor figures of reference marked thereon, which form a part of thisspecification.

My invention relates to certain new and useful improvements inswaging-blocks,which are adapted to be applied to anvils, the object ofthe same being to provide a means whereby pieces of metal maybe rounded,my improved swaging-block providing a device whereby one person canoperate the same.

Heretofore in ordinary practice a bed-piece has been provided having agroove or semicircular recess, which is placed upon the anvil, and toswage or round a piece of metal a hammer having acorrespondingsemicircular recess is held above the bed-piece by an assistantwhilesaid grooved hammer is struck by the principal workman.

The object of my invention is to provide a means whereby the services ofan' assistant can be dispensed with; and it consists in combining withthe bed-piece an upper block with corresponding grooves, which ispivoted thereto.

In the accompanying drawings, Figure 1 isl a side view of myimprovement, partiallyin section, showing the same applied to an anvil.Fig. 2 is a detail perspective view.

A refers to an anvil of ordinary construction, upon which the bed-pieceB is adapted to be placed, the downward projection b thereofV entering asuitable recess in the anvil. This bed-piece B of the swaging-block isprovided on its upper surface with transverse semicircular recesses c ofdiiferent sizes, and at one end of the same'is secured a link, C, whichprojects upwardly from the bed-piece. To this link C is secured theupper portion, D, of the swaging-block, which is provided withcorresponding semicircular grooves, the outer end of the same beingbifurcated and provided with a transverse pin, d, for secur- ,theopposite side Serial No. 284,138. (No model.)

ing the link O thereto. The upper portion of the swaging-blockL D ispreferably of less width than the bed-piece B, and its end opposite thepivot is inclined upwardly and outwardly, so that the operator canreadily raise the same with his hammer. It will also be observed thatthe portion D is pivoted to one side of the center of the base-block B,which provides at 'one side straight edges, while on is a step orportion in which the metal will lie without being swaged, this beingdesirable in forming bolts having square shoulders and similar classesof work.

The link C, which secures the upper portion of the swage-block D to thebed-piece B, is slotted, as shown, so as to allow a vertical movement ofthe parts upon each other.

In swaging bars of metal with my improved device they are heated andplaced between the swage-blocks, and held in proper position while theartisan strikes the upper surface of the pivoted portion D with ahammer.

I claim- I. In combination with an anvil, a bedpiece, B, having adownward projection, b, on its under side, the upper face of saidbedpiece being provided with transverse grooves, the portion D, of lesswidth than the bedpiece, said portion being pivoted to the bedpiece, theend opposite the pivot being inclined outwardly and upwardly,substantially as shown, and for the purpose set forth.

2. The attachments for anvils herein described, consisting of abed-piece, B, having transverse semicircular grooves, and portion D,pivoted thereto and provided with corresponding grooves, for the purposeset forth.

3. The improved swaging-block herein described, consisting of abed-piece, B, having downward projection b, for securing the same to ananvil, link C, having slotted portions, through which t-he pivot-pinspass, and portion D, pivotally secured to the bed-piece, so as to becapable of a vertical movement therein when in a horizontal position,substantially as and for the purpose set forth. i

In testimony whereof I aflix my signature in presence of two witnesses.

JOSEPH TAYLOR.
